Will resigning from my job after receiving the Destination Thailand Visa affect re-entry to Thailand?

In fact I asked ChatGPT and it's claiming the opposite:

Legally: the qualifying DTV criteria (e.g., proof of funds ≥ 500,000 THB and proof of purpose such as remote work or a soft-power activity) are requirements at the time you apply for the visa and again if/when you apply for an in-country 180-day extension of stay. They are not framed in the published rules as “continuous” conditions you must maintain every day during a current, already-granted permission to stay.

What you do have to maintain while you’re in Thailand are the general, ongoing immigration obligations (e.g., 90-day reporting and not undertaking local Thai employment without the proper authorization). Those obligations come from the Immigration Act (Section 37) and the DTV implementing order, not from the DTV qualifying proofs themselves.

So, to your examples, dropping below 500,000 THB or pausing the activity you used to qualify doesn’t automatically void your current stay. Those proofs matter again when you ask Immigration for the optional in-country 180-day extension (the extension is explicitly provided for DTV, processed by Thai Immigration).

Sources: the MFA’s official DTV notice (which lists the required documents and the 180-day stay/extension structure) and consular pages describing DTV scope; the Immigration Act for the ongoing reporting duty. None of these publications state a legal requirement to continuously maintain the 500,000 THB balance or to keep the qualifying activity active throughout the stay—only that you must show them for issuance (and, in practice, for an in-country extension).

If you want the exact implementing reference: Thai Immigration Bureau Order No. governs DTV stays and reporting; the MFA/consulate materials above are the publicly available, official guidance most officers follow.

Obviously ChatGPT can sometimes give wrong wrong information, so if you have a source for your claim I would be very curious. That said, this was the paid version of GPT-5 and it cited several sources.
